lebesgue_test, a FORTRAN90 code which calls lebesgue(), which is given a set of nodes in 1D, and plots the Lebesgue function, and estimates the Lebesgue constant, which measures the maximum magnitude of the potential error of Lagrange polynomial interpolation, and which uses gnuplot to make plots of the Lebesgue function.

lebesgue, a FORTRAN90 code which is given a set of nodes in 1D, and plots the Lebesgue function, and estimates the Lebesgue constant, which measures the maximum magnitude of the potential error of Lagrange polynomial interpolation, and which uses gnuplot() to make plots of the Lebesgue function.
The test programs create plots of the Lebesgue function for specific sizes of the point sets.
